If the display is stuck on 2H it often means the heater is not working. If the water is not heated, the cycle will never complete. It is possible the heating element is bad, but a more likely problem is with the control module PC board. The solution requires some basic repair and soldering skills plus the tools to do the job. Bosch recommends re-soldering the connection to the heating element relay (see page 11 of "SHU/SHI/SHV Dishwasher Troubleshooting Tips") free download here The problem is that the circuit board copper is not heavy enough to handle the heating element current, causing the copper to heat and melt the solder connection. A better solution is to solder a short length of copper wire between the two pins to provide more copper and reduce the chance of heating as shown in the attached photo.
